+config CAN_VCAN
+ tristate "Virtual Local CAN Interface (vcan)"
+ ---help---
+ Similar to the network loopback devices, vcan offers a
+ virtual local CAN interface.
+
+ This driver can also be built as a module. If so, the module
+ will be called vcan.
+
+config CAN_SLCAN
+ tristate "Serial / USB serial CAN Adaptors (slcan)"
+ depends on TTY
+ ---help---
+ CAN driver for several 'low cost' CAN interfaces that are attached
+ via serial lines or via USB-to-serial adapters using the LAWICEL
+ ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
+
+ As only the sending and receiving of CAN frames is implemented, this
+ driver should work with the (serial/USB) CAN hardware from:
+ www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
+
+ Userspace tools to attach the SLCAN line discipline (slcan_attach,
+ slcand) can be found in the can-utils at the SocketCAN SVN, see
+ http://developer.berlios.de/projects/socketcan for details.
+
+ The slcan driver supports up to 10 CAN netdevices by default which
+ can be changed by the 'maxdev=xx' module option. This driver can
+ also be built as a module. If so, the module will be called slcan.
+
+config CAN_DEV
+ tristate "Platform CAN drivers with Netlink support"
+ default y
+ ---help---
+ Enables the common framework for platform CAN drivers with Netlink
+ support. This is the standard library for CAN drivers.
+ If unsure, say Y.
+
+if CAN_DEV
+
+config CAN_CALC_BITTIMING
+ bool "CAN bit-timing calculation"
+ default y
+ ---help---
+ If enabled, CAN bit-timing parameters will be calculated for the
+ bit-rate specified via Netlink argument "bitrate" when the device
+ get started. This works fine for the most common CAN controllers
+ with standard bit-rates but may fail for exotic bit-rates or CAN
+ source clock frequencies. Disabling saves some space, but then the
+ bit-timing parameters must be specified directly using the Netlink
+ arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
+ If unsure, say Y.
+
+config CAN_LEDS
+ bool "Enable LED triggers for Netlink based drivers"
+ depends on LEDS_CLASS
+ select LEDS_TRIGGERS
+ ---help---
+ This option adds two LED triggers for packet receive and transmit
+ events on each supported CAN device.
+
+ Say Y here if you are working on a system with led-class supported
+ LEDs and you want to use them as canbus activity indicators.
+
+config CAN_AT91
+ tristate "Atmel AT91 onchip CAN controller"
+ depends on (ARCH_AT91 || COMPILE_TEST) && HAS_IOMEM
+ ---help---
+ This is a driver for the SoC CAN controller in Atmel's AT91SAM9263
+ and AT91SAM9X5 processors.
+
+config CAN_TI_HECC
+ depends on ARM
+ tristate "TI High End CAN Controller"
+ ---help---
+ Driver for TI HECC (High End CAN Controller) module found on many
+ TI devices. The device specifications are available from www.ti.com
+
+config CAN_BFIN
+ depends on BF534 || BF536 || BF537 || BF538 || BF539 || BF54x
+ tristate "Analog Devices Blackfin on-chip CAN"
+ ---help---
+ Driver for the Analog Devices Blackfin on-chip CAN controllers
+
+ To compile this driver as a module, choose M here: the
+ module will be called bfin_can.
+
+config CAN_JANZ_ICAN3
+ tristate "Janz VMOD-ICAN3 Intelligent CAN controller"
+ depends on MFD_JANZ_CMODIO
+ ---help---
+ Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which
+ connects to a MODULbus carrier board.
+
+ This driver can also be built as a module. If so, the module will be
+ called janz-ican3.ko.
+
+config CAN_FLEXCAN
+ tristate "Support for Freescale FLEXCAN based chips"
+ depends on ARM || PPC
+ ---help---
+ Say Y here if you want to support for Freescale FlexCAN.
+
+config PCH_CAN
+ tristate "Intel EG20T PCH CAN controller"
+ depends on PCI && (X86_32 || COMPILE_TEST)
+ ---help---
+ This driver is for PCH CAN of Topcliff (Intel EG20T PCH) which
+ is an IOH for x86 embedded processor (Intel Atom E6xx series).
+ This driver can access CAN bus.
+
+config CAN_GRCAN
+ tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices"
+ depends on OF && HAS_DMA
+ ---help---
+ Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN.
+ Note that the driver supports little endian, even though little
+ endian syntheses of the cores would need some modifications on
+ the hardware level to work.
+
+config CAN_RCAR
+ tristate "Renesas R-Car CAN controller"
+ depends on ARM
+ ---help---
+ Say Y here if you want to use CAN controller found on Renesas R-Car
+ SoCs.
+
+ To compile this driver as a module, choose M here: the module will
+ be called rcar_can.
+
+config CAN_SUN4I
+ tristate "Allwinner A10 CAN controller"
+ depends on MACH_SUN4I || MACH_SUN7I || COMPILE_TEST
+ ---help---
+ Say Y here if you want to use CAN controller found on Allwinner
+ A10/A20 SoCs.
+
+ To compile this driver as a module, choose M here: the module will
+ be called sun4i_can.
+
+config CAN_XILINXCAN
+ tristate "Xilinx CAN"
+ depends on ARCH_ZYNQ || ARM64 || MICROBLAZE || COMPILE_TEST
+ depends on COMMON_CLK && HAS_IOMEM
+ ---help---
+ Xilinx CAN driver. This driver supports both soft AXI CAN IP and
+ Zynq CANPS IP.

+ a problem with CAN support and want to see more of what is going
+ on.
